Abstract: The concept of an intersection body is central for the dual Brunn-Minkowski theory and has also played an important role in the solution of the Busemann-Petty problem. A more general concept of $ k$-intersection bodies is related to the generalization of the Busemann-Petty problem. In this note, we compare classes of $ k$-intersection bodies for different $ k$ and examine the conjecture that these classes increase with $ k$. In particular, we construct a $ 4$-intersection body that is not a $ 2$-intersection body.
